. A Industrial Minemls 157
named Madern Building Industry PK., lacated in Awash, which is
engaged in processing a dolomitic marble' in order to manuf..~
a standardized filler mineral at the required micro sizes. At t$gJ
moment this company is supplied with the dolomitic marble from*
the Kenticha Precambrian racks. The application of gypsum as a
soil amendment for ahline soils on S-deficient soils and for
groundnut production should be agronumically t d . Gypsum
deposits should also be tested on the acid soils of westem Ethiopia,
especially in acid soils with high Al-toxicities.
Local resources of agricultural limestones and dolomites, as
well as gypsum, should be investigated for their potential to
ameliorate acid and Al-toxic soils, As in many countries, these
morns of 'aglime' and dolomite have largely been overlooked.
Research should be carried 'out to determine cost-effective
extraction and low-cust crushing and grinding technologies
I followed by demonstration of the apnomic effectiveness of
liming materials and gypsum on acid soils. Further exploration and
' testing of their suitability and agronomic effectiveness are neded.
In addition, it is important to demonstrate the benefits of using
I local lirnestone/dolomite and gypsum to farmers.
